Thank You SOOO very much for fixing our DuraMax so reasonably and thoroughly. I sell parts to Every shop in town and this is who I chose to do repairs on my personal vehicle. Terry De Waal is Honest, Professional, More than qualified, Friendly and Thorough! He not only fixed my truck, he checked over Everything and explained codes I didn't know were there and what I Needed to repair and why. His integrity is without question. It's hard to find an honest and trustworthy mechanic. Oh and YES, they can work on Diesels and do Major repairs!!! I will be sending Everyone to see Terry and crew! You guys are The Best!
